Description

Technical Field

[0001] The present invention relates to the field of industrial open fill cooling towers, and more particularly to a cooling tower that facilitates installation and maintenance of fill modules. Background Art

[0002] Cooling towers are a primary industrial cooling system. Their principle is to distribute cooling water evenly through the packing through a water distribution system, creating moist, hot air. Simultaneously, a fan or thermodynamic principle forces the moist, hot air out, while dry, cool air flows in from the bottom or sides, achieving a cooling effect. The packing is a crucial component of a cooling tower, accounting for 50%-70% of the cooling efficiency. However, existing cooling towers have the following disadvantages: 1. After a period of use, dirt such as mud accumulates on the packing, affecting the tower's heat exchange efficiency and requiring regular cleaning or replacement. 2. Currently, most cooling tower packing is in sheet form, connected by adhesive or perforation, making installation and subsequent maintenance extremely inconvenient. Furthermore, the packing blocks tend to loosen and, as they accumulate more dirt, they can fall and deform under the influence of gravity.

[0003] The utility model of application number 202221300937.7 discloses a cooling tower filler with high efficiency in collecting water and dissipating heat, comprising a filler sheet with a corrugated structure, wherein the filler sheet comprises a flat portion located in a horizontal plane and a concave portion below the flat portion, and the filler sheets are stacked. The utility model designs a filler sheet with a corrugated structure, wherein a flat portion and a concave portion with water holes are provided on the filler sheet, and a support sheet with a strip is provided under the flat portion, and an arc sheet with water holes is provided in the concave portion, and the stacked filler sheets form a partition through the support sheet; at the same time, support plates with sockets and clamps are provided at both ends of the filler sheet, slots are provided on the support plate, and waterproof breathable sheets are provided between the slots so that the filler sheet group is clamped and held in place by the two groups of support plate components, and the waterproof breathable sheets on the support plate can be used to allow external air to enter to assist in heat dissipation and prevent water from overflowing and flowing turbulently, thereby improving the problem that the sheet structure is prone to collapse and instability after being watered, which greatly reduces the heat dissipation effect.

[0004] However, the above patents are similar to the existing technologies and have the following technical defects: 1. After the cooling tower has been used for a period of time, dirt such as mud will adhere to the filler, affecting the heat exchange efficiency of the cooling tower; 2. To ensure the cooling efficiency of the cooling tower, the filler needs to be cleaned or replaced regularly, but the above patented technology cannot solve the problem of quickly replacing the filler; 3. The structure of the filler sheet is relatively complex, and the assembly and disassembly processes are cumbersome. Summary of the Invention

[0041] The filling area of ​​the cooling tower body 1 is provided with a filling frame 14 with a frame structure. The filling frame 14 is close to the air inlet guide grille 2 and is divided into a plurality of filling areas.

[0042] The packing portion includes multiple independent packing units, and multiple packing areas correspond one-to-one to multiple packing units. The packing unit includes two side plates 7, multiple locking components and multiple corrugated packing sheets 6. The two side plates 7 are arranged in parallel and spaced apart, and the two side plates 7 are fixed by multiple locking components.

[0043] The locking assembly includes two reinforcement strips 51, two tighteners 52 and two pull rods 53. The reinforcement strips 51 are respectively fixed on the side walls of the two side panels 7, and the two ends of each reinforcement strip 51 extend outward from the side panels 7. The filling frame 14 in each filling area is provided with a plurality of limiting grooves 14a that cooperate with the reinforcement strips 51 on both sides of the side panels 7.

[0044] The pull rod 53 includes a first rod body 53a on the outside and a second rod body 53b on the inside. Each reinforcement strip 51 has a groove 51a at both ends that cooperates with the first rod body 53a or the second rod body 53b, and the side wall of the outer end of the first rod body 53a and the side wall of the inner end of the second rod body 53b are extended with an outer convex ring 53c that cooperates with the corresponding groove 51a.

[0053] The only difference between this embodiment and the first embodiment is that in this embodiment, the limiting column 61' of the corrugated filler piece 6' is provided with a limiting groove 61b' and a limiting protrusion 61a' at both ends respectively, and the limiting groove 61b' of the limiting column 61' of any corrugated filler piece 6' cooperates with the limiting protrusion 61a' of the corresponding limiting column 61 of the adjacent corrugated filler piece 6'.

[0054] The corrugated filling pieces 6 ′ are hard-connected in the form of the limiting grooves 61 b ​​′ and the limiting protrusions 61 a ′ of adjacent limiting columns 61 , which is more stable and safer than the existing soft connection between the corrugated filling pieces 6 ′.

[0055] The above are only two embodiments of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the principles of the present invention, and these should also be regarded as falling within the scope of protection of the present invention.
